Can I buy gold from a third party website?

The only place where Gold is available for sale is through purchasing it in VEGA Conflict itself. Any third party website offering to sell you Gold outside of the game (usually at a large discount) is making a false claim; not only will you not receive the Gold they offered, but this is almost assuredly a phishing scam aimed at compromising your account, and you may lose access to your base indefinitely.
